MUD-LUG FOR PROPELLING AUTOS.

Specification of Letters Patent.

Patented Mar. 6, 1917.

Application filed August 28, 1916. Serial No. 117,266.

the device rigidly lmt adjustahly and re movably to a wheel, and to improve the spuds and the means whereby the spuds are adjustably assembled'with the body.

It is within the province of the disclo sure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a portion of a vehicle wheel whereunto the device forming the subject matter of this application has been applied;

Fig. 2 shows the structure forming the subject matter of this application in elevation;

' Fig. 3 is a section taken on the line 3-3 of Fig. 2;

Fig. 4 is an elevation showing one 'of the spuds.

Fig. 5 p

Fig. 6 shows the complete device in bot tom plan; and

shows the complete device in top bqfi Fig. 7.is a fragmental view similar to Fig. 2, but showing the spuds reversed.

In the accompanying drawings, the numeral 1 designates a portion of the rim of a vehicle Wheel connected by means of spokes 2 with a hub 3. The rim 1 is shown as carrying a tire 4.

In putting the present invention in practice there is provided a body 5 which extends transversely of the rim 1, and having a seat 6 in which the inner edge of the rim 1. is received, the body including side arms '7 which project laterally beyond the seat 6 'and beyond the side faces of the rim '1. Mounted on the side arms 7 are standards 8. Spuds 9 are overlappwl on the standards S Eind extend longitudinally thereof, the spuds 5) being provided with laterally projecting,extensions 10 which extend in opposite directions away from the median plane of the wheel. ll desired, the spuds 9 may be reversed on the standards 8, and then the extensions 10 will overhang the tread portion of the tire l.- The. spuds 9 are equipped with longitudinal slots 11 receiving connecting devices 12, which may be bolts, the connecting devices being mounted in the standards 8. The spuds 9, in view of the construction last above described, are so mounted onthe standards 8 that the spuds may be moved inwardly and outwardly, with respect to the center of the wheel, so that the outer ends of the spuds will project beyond the periphery of the tire 4 and enable the outer ends of the spuds to secure a hold on the ground. Further,

this adjustment permits the device to be used in connection with tiresof different diameters.

Secured to and projecting inwardly from the seat portion 6 of the body 5 is a stem 14 preferably of conical form, for strength, and threaded at its inner endas shown at 15. Onto the end 15 of the stem 14 is threaded one end 17 of a loop 16.

The numeral 18 designates a head which In practical operation, the Wedge-shaped head 18 is seated between the spokes 2 as The loop 16 then is retated, and the body 5 is carried outwardly until the inner curve of the rim 1 is firmly engaged in the seat 6. Thespnds 9 project beyond the periphery of the tire 4 and a0- quire a firm hold on the ground, whereby a stalled wheel may be lifted readily out of the mud. As hereinbefore pointed out, owing to the connection between the standards 8 and the spuds 9, including the slots 11 and the damping devices 12, the spuds 9 may be adjusted. inwardly and outwardly, in a radial. direction, so that the spnds will have a firm hold on the ground.

it has been intimated hereinbeforethat the spuds may be reversed so that their eX- tensions 1O overhang the tire. Tlie spuds are shown thus arranged in Fig. 7 ot the drawings.

Having thus described the invention, what is claimed is i 1. In a device of the class described, a rim-engaging body; a longitudinally extensible connection uniting the body and the head; standards carriedby the body at the sides thereof; spuds shown in Fig.

a. spoke-engaging head;

narneoe mounted on the standards for adjustment longitudinally of the standards, toward and a way from the head; and means for holding; the spuds on the standards in adjusted positions.

2. In a device of the class described, a body provided intermediate its longitudinal edges with a rinnreceiving seat, and provided. along its longitudinal edges with laterally projecting side arms; standards projecting from the side arms; spuds mounted on the standards and. extended longitudinally thereof; slot and clamping device coaxnections between the spuds and the stand ards, whereby the spuds may be adjusted longitudinally of the standards; a wedgeshaped spokee11gaging head; a stem carried by the body; a stem carried by the head; and a nut threaded in opposite directions on to both stems.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
